The previously announced PlayStation 3 2.30 firmware update is now live, bringing with it a new PlayStation Store and DTS-HD Master Audio Support. To see more detail on the DTS audio support, click here, or hit the jump for the release. We're happy that Sony's finally revamped the store—the original one really was designed with less of a controller and more of a mouse in mind for navigation. The new store feels much more refined with the navigation menu running down the left.

Additionally, the DTS-HD High Resolution Audio codec allows content creators to deliver uncompromised, high-definition audio on Blu-ray, while requiring less disc space than DTS-HD Master Audio. DTS-HD High Resolution Audio streams audio at a high constant bit rate of 6.0 Mbps on Blu-ray discs, and is also capable of up to 7.1 audio channels at 96k sampling frequency/24 bit depth resolution, thereby producing outstanding sound quality.

Beyond enhancing PS3's audio capabilities, installing the latest system software update will also enable users to seamlessly access the new, more dynamic interface and enhanced navigation of the PLAYSTATION Store. As part of a revamp, the PLAYSTATION Store will transition from an integrated online storefront to an application living natively on PS3, enabling customers to more easily and quickly locate and purchase games, and download demos, game videos, Blu-ray movie trailers and other game-related content for PS3.
